Application led April 27, 1923. Serial No. 635,111.,

My invention relates shoe treads.

Broadly it is the object of my invention to provide a cushioned tread of this Ykind s adapted particularly, though not exclusively for athletic shoes, said tread embodying integral sole and heel members,.pneumatically cushioned to promote the comfort of the wearer. 1 A further object is to provide a hollow shoe tread of the present nature equipped with internal shape retaining reinforcing members, certain of said members forming l suction cups at the bottom of the tread to prevent slipping.

Another object is to supply a tread of this kind designed for ready and permanent application to the-ordinary shoe sole.

With the foregoing and other objects in view, which will appear in the following description, the invention resides inv the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed. Y

z 1 In the drawings, Fig. 1 is a bottom view of a shoe tread embodying my invention; Fig. 2 is a sectional view of a tread taken as n the line 2-2 of Fig. 1, said tread being shown attachedl to a shoe which is shown 30 partly in section and partly diagrammatica'lly; Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2; Fig. 4: is a sectional vlew taken on the line 4-'-4 of Fig. l and Fig. 5 is a similar view taken on the line 5 5 of Referring tothe drawings, wherein similar reference characters have been usedto indicate similar parts throughout the several views, it will be observed that-my kimproved m tread serves as an outsole and comprises a combined sole and heel structure designed for application to the sli -sole of a shoe. Figs. 2, 4 and 5 illustrate t e tread sewed to the 'slip-sole 1() of a shoe 11. Thev tread in- M cludes a sole section A and a heel section B,

' said sections being integral. 'Ihe structure is made 'up of a top piece 12, bottom pieces 13 and 14 of the' sole and heel sections A and B, sides 15 of the former and sides 16 of the latter and a front or riser 17 of the heel section B. Strengthening webs a; between the upper land lower pieces 12 and 13, at the shank of the tread, reachv inward from the sides, but do not meet at their inner edges. l This arrangement provides a duct which to improvements in from their part in reinforcing brings the hollow lsole and heel sections into communlcation with each other. An endless recess 18 cast in the sides of the structure provides a marginal Hange19 at the upper edge of the structure through which a seam 20 is passed in sewing the` tread to a shoe sole. In both the. sole and heel sections are a p1urality of interspered, inverted cup-like members 2l. The crowns of these members 21 are integral with Athe top piece 12, while the margins of said members, near the rims 21W thereof, are integral with the bottom pieces 13 and 14. In addition to reinforcing the tread structure, the cup-like members 21 supply non-slipping suction cavities, the rims 2la of said members being readily conformable with slight irregularities in a supporting surface to enhance the gripping of the surface by suction. Said rims 2la also supply non-slipping projectons, the action. of which supplements the suction gripping action of the tread structure. To further reinforce thetread longitudinally, I supply longitudinal ribs 22 `cast integrally with the` top piece 12. The sole and 'heel sections A and B being in communication one with the other as shown in Figs. 2 and 3, it will be understood that a hollow unitary structure is comprised thereby. lIn the front or riser 17 of the heel section B, I insert an air valve 23 of conventional type to which an air pump may be removably attached for the purpose of inflatin the tread and lendinggreater resiliency t ereto.-

Being preferably formed of a good grade of live rubber the tread is relatively light in weight and under the foot of the wearer. The suction cup members 21, aside the structure, voperate effectively as non-slippin elements, not only upon a ioor, but upon tie ground, as well. j f

Changes in the specific form of my invention, as herein disclosed, 1 may be made within the scope of what is claimed without departing from the spirit of my invention.

'Having described my invention, what I claim as new and desire to protect by Letters Patentis:

1.
